Oregon Description

United States a large stake in the land.

Spain ceded their earlier claims on this land to the United States, although the British disputed it and the area existed for several decades under contentious joint control.

The Oregon Trail: A New Frontier

With the opening of the Oregon Trail in 1841, pioneers settled in the fertile Willamette Valley. Gold discoveries in the high country and along the coast led to further settlement. However, these provoked tragic wars with the Native Americans, which concluded with the Indians surrendering of all their lands.

Settlers met in 1843 to address the menace of wild animals. These "Wolf Meetings" led to a drafting of a constitution and the formation of Oregon's first government, which included both American and British participation.
